TL;DR: The use of metakaolin (MK) as a pozzolanic material for mortar and concrete has received considerable attention in recent years as mentioned in this paper, which is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement consumption, the manufacture of which being environmentally damaging.

TL;DR: In this paper, the role of metakaolin (MK) in enhancing the strength of concrete is reviewed and principal mechanisms identified, and the observed results establish that there is an optimum OPC replacement level of 20 wt% MK and that the contribution which MK makes to strength is restricted beyond 14 days.

TL;DR: In this article, the porosity and pore size distribution of cured OPC-metakaolin paste was investigated and it was found that the proportion of large pores (radius > 0.02) in the paste decreases with both increase in metakaolin content and increase in curing time.

TL;DR: The use of ground granulated blast furnace slag (GGBS) is well established as a binder in many cement applications where it provides enhanced durability, including high resistance to chloride penetration, resistance to sulphate attack and protection against alkali silica reaction (ASR) as discussed by the authors.

TL;DR: The use of ground granulated blastfurnace slag (GGBS), an industrial byproduct, is well established as a binder in many cement applications where it provides enhanced durability and high resistance to sulphate attack.
